Bought to install at home but new technology made installation a much easier option.  So this unit has been in my shed ever since, unused and still in its original packaging.  I have assembled and tested the system and all works.  Will suit domestic installation or small business unit as a cheap and effective security system.  Detailed instruction manual included. All you need for installation is a screwdriver and a TV monitor (HDMI, BNC and VGA connection).  All cabling including 18 Metre camera cable for each camera is included.  Happy for buyer to collect for free.
